Take a look at the Slingshot Hover Glide 46cm Aluminium Mast with S2AS!

The 46cm (18inch) Slingshot Aluminium mast is the perfect size for your first foiling experience. Less riding height, means a shorter distance to fall, and it also means that you can have a lot more input on the wings below you to begin with. Already foiling, but your spot is always shallow or has a large tidal range? The the shorter foil will save any scuffs on the sea floor.
